The main display window is a 3D view centered on a 3D geosphere. It provides functions such as data loading, comparison, display, editing, and scene simulation.
The “View image” tab includes four modules: “image adjustment,” “spatial measurement,” “navigation,” and “view” for adjustment, navigation, and browsing of the current 3D geosphere (Figure 2-15).

The “image adjustment” module includes “colorbar,” “brightness,” “contrast,” “transparency,” and “color bar” switch buttons.

Figure 2‑16. Colorbar
The “colorbar” is the render method of image display mainly for raster data. Click "colorbar” " to pop up the raster data rendering dialog box (Figure 2-17). The raster data rendering dialog box includes two tabs: classified rendering and stretch rendering.
In “classified rendering,” the user can select the default product color label template in the system through the pull-down box to render the layer (Figure 2-17). The user can also click user-defined class to render the layer.
Click "stretch render," and the stretch render tab will pop up (Figure 2-18). User completes the setting of the stretching colorbar by selecting the color band (reversible) and stretching type (such as standard deviation, maximum/minimum values).
